Led lamp including refractive lens element

ABSTRACT

A lamp includes one or more LED&#39;s which illuminate respective portions of a refractive lens element whose incident surface preferably includes portions of hyperboloids which translate the LEDs&#39; emitted rays into substantially parallel beams within the lens element. The lens element&#39;s exit surface is preferably an array of facets configured to provide a desired beam spread pattern, allowing precise tailoring of the resultant output beam pattern. The plurality of facets also allows a larger area on the lamp to appear to viewers to be uniformly illuminated, thus providing full target size definition at a decreased cost and with reduced power consumption. &lt;IMAGE&gt;   &lt;IMAGE&gt;
